radv: call nir_copy_prop() after load-store vectorization

Browse Source 
The load-store vectorizer can create a large amount
of unnecessary nir_op_vec and nir_op_mov instructions.
This prevents nir_opt_move from stalling to much and
potentially also helps other passes.

Closes: #4778
Fixes: 1958381c9a ('radv: Reorder some NIR optimizations in preparation for the I/O changes.')
